6、h a manner asto provide a continuous mesh without knots or ties except inthe form of knuckling, or of twisting the ends of the wires toform the selvage of the fabric.3.1.2 diamond countthe number of diamond openingsfrom one edge of the fabric to the other. The diamond count ofa given fabric shall be
7、gin at the first completed diamond at oneedge and continue to the unfinished half or full opening at theother edge.3.1.3 knucklinga term used to describe the type of selvageobtained by interlocking adjacent pairs of wire ends and thenbending the wire ends back into a loop. The loop shall beclosed or
8、 nearly closed to a measurement less than the diameterof the wire.3.1.4 twistinga term used to describe the type of selvageobtained by twisting adjacent pairs of wire ends together in aclose helix of 112 machine turns, which is equivalent to threefull twists, and cutting the wire ends at an angle. T
9、he wire endsbeyond the twist shall be at least14 in. 6.4 mm long. Thistype of selvage is not used on fabric with a mesh size of lessthan 2 in. 50.8 mm.4.

15、 the class of coating specified (Class 1 or Class 2).6. Weave6.1 The wire shall be woven throughout in the form ofapproximately uniform square mesh, having parallel sides andhorizontal and vertical diagonals of approximately uniformdimensions. The top and bottom of the fabric shall be knuckledor twi
16、sted as specified in Section 10.6.2 Typical diamond count for each standard height isshown in Table 1. Other diamond counts are permissibleprovided that they are consistent within a lot. The purchaserhas the option to specify the diamond count (4.1.5).7. Size of Mesh7.1 The size of mesh shall be as
17、indicated in Table 2.7.2 The permissible variation from the specified size ofmesh shall be 618 in. 63.2 mm for all mesh sizes except 1in., and 6116 in. 61.6 mm for 1 in. mesh size.7.3 The size of mesh shall be determined by measuring theminimum clear distance between the wires forming the parallelsi
18、des of the mesh and determined as the average of tworeadings taken at right angles to each other.8. Size of Wire8.1 Chain-link fabric shall be fabricated from wire diam-eters as listed in Specification A 817, with a permissiblevariation from the specified diameter of the coated wire of60.005 in. 60.
19、13 mm.9. Height of Fabric9.1 Chain-link fabric shall be furnished in the standardheights shown in Table 2. The height of fabric shall be theoverall dimension from ends of twists or knuckles. Thepermissible variation from the specified height shall be 61 in.625 mm for standard selvage.10. Selvage10.1
20、 Unless otherwise specified by the purchaser, fabricswith 2- or 218-in. 50- or 54-mm mesh, in heights 60 in. 1520mm and under shall be knuckled at both selvages. Fabric 72in. 1830 mm high and over shall be knuckled at one selvageand twisted at the other.10.2 The selvages of fabrics with meshes of le
21、ss than 2 in.50 mm shall be knuckled.NOTE 2Caution: Twisted selvages for fence fabric under 72 in. 1830mm in height are not recommended because of consumer safety consid-erations.11. Weight of Coating11.1 The weight of Zn-5A1-MM alloy coating on the fabricmay be ordered in two coating weight classes
22、 as follows, inaccordance with Specification A 817.11.1.1 Class 1The weight of Zn-5A1-MM alloy coatingshall not be less than 0.6 oz/ft2183 g/m2 of uncoated wiresurface.11.1.2 Class 2The weight of Zn-5A1-MM alloy coatingshall not be less than 1.0 oz/ft2305 g/m2 of uncoated wiresurface.11.2 The weight
23、 of coating shall be determined in accor-dance with Test Method A 90.12. Workmanship12.1 Chain-link fence fabric shall be produced by methodsrecognized as good commercial practices.12.2 Excessive roughness, blisters, and flaking shall benoted. These and other defects, if present to any considerablee
24、xtent, shall provide a basis for rejection.NOTE 3Rust formations on the cut ends of the wire at the fabricselvages are inherent characteristics of this material and do not warrantrejection of the fabric.13. Standard Length of Rolls13.1 The standard length of roll shall be 50 ft 15.24 m 61 % except a
25、s otherwise agreed upon at the time of purchase.TABLE 1 Typical Diamond CountANominal Di-ameterCoatedWire, in.Size ofMesh, in.Height of Fence Fabric, in.36 42 48 60 72 84 96 108 120 1440.192 2 1012 1212 1312 1712 2012 2412 2712 3112 3412 41210.148 2 1012 1212 1312 1712 2012 2412 2712 3112 3412 41120
